Connie was accustomed to Kensington or the Scotch hills or the Sussex downs: that was her England. With the stoicism of the young she took in the utter, soulless ugliness of the coal–and–iron Midlands at a glance, and left it at what it was: unbelievable and not to be thought about. From the rather dismal rooms at Wragby she heard the rattle–rattle of the screens at the pit, the puff of the winding–engine, the clink–clink of shunting trucks, and the hoarse little whistle of the colliery locomotives. Tevershall pit–bank was burning, had been burning for years, and it would cost thousands to put it out. So it had to burn. And when the wind was that way, which was often, the house was full of the stench of this sulphurous combustion of the earth’s excrement. But even on windless days the air always smelt of something under–earth: sulphur, iron, coal, or acid. And even on the Christmas roses the smuts settled persistently, incredible, like black manna from the skies of doom.

Well, there it was: fated like the rest of things! It was rather awful, but why kick? You couldn’t kick it away. It just went on. Life, like all the rest! On the low dark ceiling of cloud at night red blotches burned and quavered, dappling and swelling and contracting, contracting like burns that give pain. It was the furnaces. At first they fascinated Connie with a sort of horror; she felt she was living underground. Then she got used to them. And in the morning it rained.

Clifford professed to like Wragby better than London. This country had a grim will of its own, and the people had guts. Connie wondered what else they had: certainly neither eyes nor minds. The people were as haggard, shapeless, and dreary as the countryside, and as unfriendly. Only there was something in their deep–mouthed slurring of the dialect, and the thresh–thresh of their hob–nailed pit–boots as they trailed home in gangs on the asphalt from work, that was terrible and a bit mysterious.

There had been no welcome home for the young squire, no festivities, no deputation, not even a single flower. Only a dank ride in a motor–car up a dark, damp drive, burrowing through gloomy trees, out to the slope of the park where grey damp sheep were feeding, to the knoll where the house spread its dark brown facade, and the housekeeper and her husband were hovering, like unsure tenants on the face of the earth, ready to stammer a welcome.

There was no communication between Wragby Hall and Tevershall village, none. No caps were touched, no curtseys bobbed. The colliers merely stared; the tradesmen lifted their caps to Connie as to an acquaintance, and nodded awkwardly to Clifford; that was all. Gulf impassable, and a quiet sort of resentment on either side. At first Connie suffered from the steady drizzle of resentment that came from the village. Then she hardened herself to it, and it became a sort of tonic, something to live up to. It was not that she and Clifford were unpopular, they merely belonged to another species altogether from the colliers. Gulf impassable, breach indescribable, such as is perhaps nonexistent south of the Trent. But in the Midlands and the industrial North gulf impassable, across which no communication could take place. You stick to your side, I’ll stick to mine! A strange denial of the common pulse of humanity.

“I believe you have hit it.”

“Not a doubt of it. It is a very urgent message, thrice repeated to make it more so. But beware of what? Wait a bit; he is coming to the window once more.”

Again we saw the dim silhouette of a crouching man and the whisk of the small flame across the window as the signals were renewed. They came more rapidly than before — so rapid that it was hard to follow them.

“PERICOLO pericolo — eh, what’s that, Watson? ‘Danger,’ isn’t it? Yes, by Jove, it’s a danger signal. There he goes again! PERI. Halloa, what on earth —”

The light had suddenly gone out, the glimmering square of window had disappeared, and the third floor formed a dark band round the lofty building, with its tiers of shining casements. That last warning cry had been suddenly cut short. How, and by whom? The same thought occurred on the instant to us both. Holmes sprang up from where he crouched by the window.

“This is serious, Watson,” he cried. “There is some devilry going forward! Why should such a message stop in such a way? I should put Scotland Yard in touch with this business — and yet, it is too pressing for us to leave.”

“Shall I go for the police?”

“We must define the situation a little more clearly. It may bear some more innocent interpretation. Come. Watson, let us go across ourselves and see what we can make of it.”

As we walked rapidly down Howe Street I glanced back at the building which we had left. There, dimly outlined at the top window, I could see the shadow of a head, a woman’s head, gazing tensely, rigidly, out into the night, waiting with breathless suspense for the renewal of that interrupted message. At the doorway of the Howe Street flats a man, muffled in a cravat and greatcoat, was leaning against the railing. He started as the hall-light fell upon our faces.

“Holmes!” he cried.

“Why, Gregson!” said my companion as he shook hands with the Scotland Yard detective. “Journeys end with lovers’ meetings. What brings you here?”

“The same reasons that bring you, I expect,” said Gregson. “How you got on to it I can’t imagine.”

“Different threads, but leading up to the same tangle. I’ve been taking the signals.”

“Signals?”

“Yes, from that window. They broke off in the middle. We came over to see the reason. But since it is safe in your hands I see no object in continuing the business.”

“Wait a bit!” cried Gregson eagerly. “I’ll do you this justice, Mr. Holmes, that I was never in a case yet that I didn’t feel stronger for having you on my side. There’s only the one exit to these flats, so we have him safe.”

“Who is he?”

“Well, well, we score over you for once, Mr. Holmes. You must give us best this time.” He struck his stick sharply upon the ground, on which a cabman, his whip in his hand, sauntered over from a four-wheeler which stood on the far side of the street. “May I introduce you to Mr. Sherlock Holmes?” he said to the cabman. “This is Mr. Leverton, of Pinkerton’s American Agency.”
